A Seamless.ai Alternative
For Cleaning the Lists You Have
Seamless.ai sells access to a large contact database. Leedrush checks the lead lists you already have — every email checked with mails.so, every lead scored by AI — and you pay only for the Hot and Warm ones.

When Leedrush Is the Better Fit
Different tools for different jobs.
You already have leads
Exports from Seamless.ai, events, LinkedIn or your CRM: upload them and every email is checked with mails.so at that moment, so you see which addresses still work before you send.
You want to know who to call first
DeepSeek AI scores every lead 0–100 against your ideal customer and gives the reason: Hot 75+, Warm 50–74, Cold below 50.
You don't want to pay for bad rows
Credits are charged only for Hot and Warm leads. Cold leads, undeliverable emails and duplicates are free, and a single file never costs more than 500 credits.
No seat fees
One account for the team: $1.99 per qualified lead with no plan, or Starter at $399/month with 2,500 leads included.
Straight into your CRM
Push Hot and Warm leads to HubSpot, Pipedrive, GoHighLevel, ActiveCampaign, Mailchimp, Reply.io, Outreach or Zapier — by hand or after each file.
New businesses with AI
No list? LGaaS Find searches a business directory by type and location and scores every result. It finds businesses, not a people database like Seamless.ai.
Questions About Switching
Does Leedrush have a contact database like Seamless.ai?
No. Leedrush works on the lists you bring, and LGaaS finds businesses in a business directory. If you need to search millions of named people, keep a database tool and use Leedrush to check and score what you export from it.
What happens to emails that don't work?
Every email is checked with mails.so before scoring. An undeliverable address always stays Cold, so it is never charged and you can leave it out of your sequence.
Can I test Leedrush on my current Seamless.ai list?
Yes. Export a sample of your contacts as CSV and upload it to Leedrush — new accounts get 500 free credits and no card is needed. You'll see each email's status and each lead's AI score.
Is there a Chrome extension?
No. Leedrush works through the dashboard, file uploads, the REST API and webhooks.
